Allow unauthenticated users to compare (#11240)

* routers: make /compare route available to unauthenticated users Remove some bits of the compare interface if the user isn't signed in. Notably, they don't need to see the "New Pull Request" button box nor the hidden form that would fail to submit due to the POST request continuing to require proper privileges. Follow-up commits will improve the UI a bit around this, removing some "Pull Request" verbiage in favor of "Compare." * ui: home: show "compare" button for unauthenticated users This change requires pulling in the BaseRepo unconditionally and recording if the pull request is in-fact not allowed (.PullRequestCtx.Allowed). If the user isn't allowed to create a pull request, either because this isn't a fork or same-fork branch PRs aren't allowed, then we'll name the button "Compare" instead of "Pull Request." * ui: branch list: use the new Compare language when available When viewing the branch listing as an unauthenticated user, you'll get "Pull Request" buttons. use the new "Compare" verbiage instead, which matches GitHub behavior when you can't issue a pull request from the branches.
